Yahya ibn Yahya narrated to us, saying: Hammad ibn Zayd informed us, from Mu'alla ibn Ziyad, from Mu'awiyah ibn Qurrah, from Ma'qil ibn Yasar, that the Messenger of Allah, peace and blessings be upon him—[and] Qutaybah ibn Sa'id also narrated it to us, saying: Hammad narrated to us, from al-Mu'alla ibn Ziyad, tracing it back to Mu'awiyah ibn Qurrah, tracing it back to Ma'qil ibn Yasar, tracing it back to the Prophet, peace and blessings be upon him, who said: "Worship during turmoil is like emigration to me."
